I am using Snell's law to try and find the index of refraction of two elements, Water and then vegetable cooking oil. I measured the Angle of incidence for water which was 45 degrees, and the angle of refraction which was 32 degrees. How do I find the Index of refraction for water?
Then I did the same thing with vegetable cooking oil. My data was:
Angle of incidence: 57 degreesAngle of refraction: 35 degrees
What would the index of refraction then be for the oil?
The nucleus of 8Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons).
